Divergent changes in plant community composition under 3-decade grazing exclusion in continental steppe. [PDF]

PLoS ONE, 2011
An understanding of the factors controlling plant community composition will allow improved prediction of the responses of plant communities to natural and anthropogenic environmental change.

Optimal Diet Selection by a Generalist Grazing Herbivore

Functional Ecology, 1995
1. We develop a stochastic dynamic programming model of grazing behaviour for a generalist mammalian herbivore. The model considers that behaviour depends upon three state variables: stored energy, digestible gut fill and indigestible gut fill. When the plant community comprises two alternative species, the animal must choose between five alternative ...

Sheep and goat feeding behavior profile in grazing systems

Acta Scientiarum: Animal Sciences, 2020
 Feeding behavior analysis provides information about the relationships between animals and pastures. Therefore, this review aims to describe some aspects of the feeding behavior profiles of both sheep and goats in grazing systems.

Towards evenly distributed grazing patterns: including social context in sheep management strategies [PDF]

PeerJ, 2016
Background. A large proportion of natural grasslands around the world is exposed to overgrazing resulting in land degradation and biodiversity loss. Although there is an increasing effort in the promotion of sustainable livestock management, rangeland ...

Performance and parasitosis in heifers grazing mixed with sows [PDF]

, 2000
The aim of the study was to investigate the effect of mixed grazing with first season heifers and pregnant sows on animal performance, gastro-intestinal helminths, pasture quality and sward structure during three grazing seasons.

Activity budget and movement patterns of Brown Swiss and Alpine Grey lactating cows during summer grazing in alpine pastures

Italian Journal of Animal Science, 2023
We used GPS tracking to monitor the grazing patterns of Brown Swiss and Alpine grey lactating cows on an alpine summer pasture (2038 m a.s.l.; SD = 146) in the Dolomites. The pasture (171 ha) was managed with a continuous grazing system (0.52 LU/ha) with

Precision Tools for Forage Assessment and Nutritional Decision Support in Grazing-Ruminant Systems: A Narrative Review

Agriculture
Spatial and temporal heterogeneity in pasture quantity and nutritive value remains a major constraint to efficient nutritional management in grazing-ruminant systems.

Native lagomorphs facilitate noxious weeds in a semi-arid rangeland

Frontiers in Ecology and Evolution, 2023
Rangeland management has traditionally focused on the grazing effects of livestock, or on wild ungulates because they are potential competitors with livestock.

Frequency Distribution of Sward Heights and Forage Species Composition in Different Integrated Crop–Livestock Systems

Grasses
Sward height is a practical indicator for defining management targets that reflect pasture structure. The complexity of integrated systems, including the coexistence of trees, crops, and livestock, can modify animal grazing distribution and microhabitat ...
